Abstract
A sleeve (11) is a hollow cylindrical member provided in a shield terminal (10), and pressable by a wire barrel (18) by being arranged between an insulating portion (63) and a shield portion (62) of a shielded cable (60). A convex portion (36) shaped to bulge radially outward over an entire circumference is provided at an intermediate position of the sleeve (11) in an axial direction. The convex portion (36) is crushed and elongated by the wire barrel (18) of an outer conductor terminal (13). The insulating portion (63) can be prevented from being excessively compressed.
Description
- The invention relates to a sleeve and a shield terminal manufacturing method.
- A shield terminal having a shielding function is connected to an end part of a coaxial cable (shielded cable). Japanese Unexamined Patent Publication No. 2010-232046 discloses a sleeve provided in a shield terminal. The sleeve is inserted between a braided wire and an insulating portion inside the braided wire on an end part of the shield terminal.
- The sleeve has a hollow cylindrical shape and is provided with projections at three positions spaced apart in a circumferential direction. The projections support the insulating portion at three points in the circumferential direction.
- A barrel is crimped to the sleeve together with the braided wire. Japanese Unexamined Patent Publication No. 2010-232046 describes that an air layer is formed between the insulating portion and the sleeve by the respective projections to compensated for an impedance reduction due to a barrel crimping operation.
- A projecting shape of each projection disclosed Japanese Unexamined Patent Publication No. 2010-232046, is maintained when and after the barrel is crimped. Thus, a tip of each projection may strongly bite into the insulating portion and the insulating portion may be partially crushed or cut when the barrel is crimped.
- In contrast, sufficient flexural rigidity may not be ensured with a general-purpose sleeve having a hollow cylindrical shape and a constant diameter over the entire length. When the barrel is crimped, the sleeve itself may be crushed to compress the insulating portion excessively.
- The invention was completed on the basis of the above situation and aims to provide a sleeve capable of preventing an insulating portion of a shielded cable from being compressed excessively and to provide a shield terminal with such a sleeve.
- A first aspect of the invention is directed to a hollow cylindrical sleeve arranged between an insulating portion and a shield portion of a shielded cable and pressable by a barrel. A convex portion is provided at an intermediate position of the sleeve in an axial direction and bulges radially outward over an entire circumference.
- A second aspect of the invention is directed to a shield terminal manufacturing method that includes arranging a hollow cylindrical sleeve between an insulating portion and a shield of a shielded cable, pressing a barrel toward the sleeve so that the barrel crushes and elongates a convex portion that bulges radially out over an entire circumference at an intermediate position of the sleeve in an axial direction and thereby connecting an outer conductor terminal to the shielded cable.
- According to the first and second aspects of the invention, the convex portion bulges radially out over the entire circumference and is provided at the intermediate position of the sleeve in the axial direction. Thus, the flexural rigidity (reaction force) of the sleeve can be enhanced. This makes the sleeve hard to crush during the pressing of the barrel, and the insulating portion will not be compressed excessively by the sleeve. Particularly, since the convex portion is provided over the entire circumference of the sleeve, a circumferentially uniform compression force can be applied to the insulating portion and the sleeve will not bite into a circumferential part of the insulating portion.
- According to the second aspect of the invention, the convex portion is crushed and elongated by the barrel. Thus, the insulating portion will not be compressed excessively by the convex portion.
- The sleeve may have a receiving base on a radially outer end part of the convex portion and extending along an axial part that is pressable by the barrel. According to this configuration, a clearance along the axial direction can be formed between the inner surface of the receiving base and the insulating portion. Thus, the insulating portion is prevented more reliably from being compressed excessively.
- An end convex portion may bulge radially out on an end part in the axial direction and may extend over an entire circumference and a concave portion may be formed between the end convex portion and the intermediate convex portion in the axial direction. According to this configuration, a convex-concave shape is formed by the end concave portion. The end convex portion and the concave portion are provided continuously on an end of the sleeve in the axial direction. Thus, the flexural rigidity of the sleeve is enhanced further and the insulating portion is prevented more reliably from being compressed excessively.
- The barrel for pressing the convex portion may be configured to contact the shield. Accordingly, flexural rigidity of the sleeve is enhanced while preventing the insulating portion from being compressed excessively.

FIGS. 1 to 6 . Asleeve 11 of this embodiment is provided in ashield terminal 10 having a shielding function, and is connected to an end part of a shieldedcable 60. - <
Shielded Cable 60> - The shielded
cable 60 is a coaxial cable and, as shown inFIGS. 3 and 4 , includes acore 61 made of a conductor for transmitting a high-frequency signal, and ashield 62 made of a braided wire surrounds thecore 61. An insulatingportion 63 made of insulating resin covers the outer periphery of thecore 61, and theshield 62 covers the outer periphery of theinsulating portion 63. Asheath 64 made of insulating resin covers the outer periphery of theshield 62. In this embodiment, a layer of ametal foil 65, such as a copper foil, is provided between theinsulating portion 63 and theshield 62. The layer of themetal foil 65 functions to adjust an impedance in a transmission path to a specified value. - The
sheath 64 is removed in a predetermined range on the end part of the shieldedcable 60 to expose an end part of theshield 62. Further, theshield 62, theinsulating portion 63 and themetal foil 65 are removed in a predetermined range to expose an end part of thecore 61. - <Shield Terminal 10>
- As shown in
FIG. 6 , theshield terminal 10 includes aninner conductor terminal 12, anouter conductor terminal 13 surrounding theinner conductor terminal 12 and a dielectric 14 interposed between theouter conductor terminal 13 and theinner conductor terminal 12 in addition to thesleeve 11. Thesleeve 11, theinner conductor terminal 12 and theouter conductor terminal 13 are made of metal, and the dielectric 14 is made of resin. - The
inner conductor terminal 12 is formed integrally, such as by bending a conductive metal plate and includes amating connecting portion 15 and a wire-side connecting portion 16. Themating connecting portion 15 is in a front part on a shown left side and is connectable to an unillustrated mating inner conductor terminal. The wire-side connecting portion 16 is in a rear part on a shown right side and forms an open barrel to be crimped to thecore 61. Themating connecting portion 15 has a tubular part elongated in the front-rear direction, and a tab of the mating inner conductor terminal is inserted into themating connecting portion 15 for connection. - The dielectric 14 includes an
accommodating portion 17 extending in the front-rear direction and open in a rear surface. Theinner conductor terminal 12 is inserted into theaccommodating portion 17 from behind. Theinner conductor terminal 12 is incorporated into the dielectric 14 with themating connecting portion 15 accommodated in theaccommodating portion 17 and the wire-side connecting portion 16 projecting rearward from the rear surface of the dielectric 14. - The
outer conductor terminal 13 is formed integrally, such as by bending a conductive metal plate and includes, as shown inFIG. 5 , a hollowcylindrical fitting 21, awire barrel 18 located behind the fitting 21, aninsulation barrel 19 behind thewire barrel 18 and acoupling 24 coupling the fitting 21 and thewire barrel 18. A barrel is constituted by thewire barrel 18 and theinsulation barrel 19. - The
fitting portion 21 accommodates the dielectric 14 inside. A forwardly openfitting space 22 is formed between the inner surface of thefitting portion 21 and the dielectric 14. An unillustrated mating outer conductor terminal is fit into thefitting space 22. The mating outer conductor terminal conductively contacts a connectingportion 23 provided in thefitting portion 21 inside thefitting space 22. - The
coupling 24 includes left andright side walls 25. The front ends of therespective side walls 25 are coupled integrally to the fitting 21 and the rear ends thereof are coupled integrally to thewire barrel 18. Left andright projections 26 project on the upper ends of therespective side walls 25. Although not described in detail, when theshield terminal 10 is inserted into an unillustrated connector housing, theprojections 26 guide the insertion of theshield terminal 10 and restrict the escape of theshield terminal 10 from the connector housing. - A
space 27 vertically penetrates aspace 27 between theside walls 25 of theouter conductor terminal 13, as shown inFIG. 6 . The wire-side connecting portion 16 of theinner conductor terminal 12 is arranged in thespace 27 and can be crimped to the core 61 by tools (crimper, anvil) entering thespace 27 from both upper and lower sides. - The
wire barrel 18 is crimped and connected to theshield 62 of the shieldedcable 60. Thewire barrel 18 is in the form of an open barrel and includes twowire barrel pieces 31 rising from both left and right sides of abottom portion 28. Eachwire barrel piece 31 is wound on the outer periphery of theshield 62. - The
insulation barrel 19 is one size larger than thewire barrel 18 and crimped and is connected to thesheath 64 of the shieldedcable 60. Theinsulation barrel 19 is an open barrel and includes twoinsulation barrel pieces 32 rising from both left and right sides of thebottom portion 28. Eachinsulation barrel piece 32 is wound on the outer periphery of thesheath 64. - <
Sleeve 11> - The
sleeve 11 is made of metal, has a hollow cylindrical shape and is inserted between the metal foil 65 (on the side of the insulating portion 63) and the 62, as shown inFIGS. 3 and 4 . Thesleeve 11 is longer than the barrel (wire barrel 18 and insulation barrel 19) in the front-rear direction. As shown inFIG. 6 , thesleeve 11 has a front pressedregion 33 to be pressed by thewire barrel 18 in a front part and a rearpressed region 34 to be pressed by theinsulation barrel 19 in a rear part. - The
sleeve 11 is formed into a hollow cylindrical shape by rolling a flat plate having a substantially rectangular shape in a developed state. As shown inFIG. 1 , butting edges 35 on both circumferential ends are provided along the front-rear direction (axial direction) in thesleeve 11. Thesleeve 11 can maintain the hollow cylindrical shape with the butting edges 35 butted against each other. - The
sleeve 11 includes aconvex portion 36 that bulges radially out over the entire circumference in the front pressedregion 33 at an intermediate position in the front-rear direction. As shown inFIG. 4 , theconvex portion 36 has a flat shape in a side view and includes a receivingbase 37 along the front-rear direction on a radially projecting end part. The receivingbase 37 has inner and outer diameters constant in the front-rear direction and larger than those of parts adjacent in the front-rear direction. The receivingbase 37 receives a pressing force (compression force) of thewire barrel 18 and faces thewire barrel 18. The receivingbase 37 is shorter than thewire barrel 18 in the front-rear direction. - The
sleeve 11 includes an endconvex portion 38 shaped to bulge radially outward over the entire circumference in a front part forward of the front pressedregion 33. The endconvex portion 38 includes an outerperipheral portion 39 along the front-rear direction on a projecting end part. The outerperipheral portion 39 has substantially the same inner and outer diameters as those of the receivingbase 37. The outerperipheral portion 39 has a length shorter than that of the receivingbase 37 in the front-rear direction and is located in the front part of thesleeve 11. The butting edges 35 are open toward the front end of thesleeve 11 in the outerperipheral portion 39. - The
sleeve 11 is formed with aconcave portion 41 between the endconvex portion 38 and theconvex portion 36 in a front part of the front pressedregion 33. As shown inFIG. 4 , front and rear end parts of theconcave portion 41 are defined by a rear end part of the end-sideconvex portion 38 and a front part of theconvex portion 36, thereby being tapered to have a smaller diameter toward a radially inner side. Aback portion 43 of theconcave portion 41 is arranged along the front-rear direction and has the same inner and outer diameters as those of parts of thesleeve 11 except theconvex portion 36 and the endconvex portion 38. Note that theconvex portion 36 and the end-sideconvex portion 38 are formed together with theconcave portion 41 by press-working the flat plate having the substantially rectangular shape in the developed state prior to the bending of thesleeve 11. - The
sleeve 11 is inserted between theshield 62 and the metal foil 65 (on the side of the insulating portion 63) in the shieldedcable 60 from the front. As shown inFIG. 3 , a front part of thesleeve 11 including the front pressedregion 33 is arranged forward of thesheath 64, and a rear part including the rear pressedregion 34 is arranged while being inserted inside thesheath 64. As shown inFIG. 4 ,clearances 20 at a given interval in the front-rear direction are formed between the receivingbase 37 of theconvex portion 36 and themetal foil 65 and between the outerperipheral portion 39 of the endconvex portion 38 and themetal foil 65. - The shielded
cable 60 is on the barrel of theouter conductor terminal 13 with thesleeve 11 mounted. Thewire barrel 18 is arranged to face the front pressedregion 33 of thesleeve 11, and theinsulation barrel 19 is arranged to face the rear pressedregion 34 of thesleeve 11. In that state, unillustrated tools (crimper, anvil) are brought into contact with thewire barrel 18 and theinsulation barrel 19 to apply a radially inward pressing force. The front pressedregion 33 of thesleeve 11 is pressed by thewire barrel 18 via theshield 62, and the rear pressedregion 34 of thesleeve 11 is pressed by theinsulation barrel 19 via theshield 62 and thesheath 64. - The
convex portion 36 is crushed together with theconcave portion 41 and the endconvex portion 38 and almost elongated forward when the pressing force of thewire barrel 18 exceeds a predetermined value. In this way, theclearances 20 formed between the receivingbase portion 37 of theconvex portion 36 and themetal foil 65 and between the outerperipheral portion 39 of the end-sideconvex portion 38 and themetal foil 65 are substantially eliminated (seeFIG. 6 ). - The front pressed
region 33 of thesleeve 11 is enhanced in flexural rigidity by the continuous convex-concave shape formed by theconvex portion 36, theconcave portion 41 and the endconvex portion 38, and is structured to be harder to crush than the rear pressedregion 34. Thus, the front pressedregion 33 of thesleeve 11 is not crushed significantly further even if theconvex portion 36 are crushed, and can prevent the insulatingportion 63 from being excessively compressed by being pressed by thesleeve 11. - The
wire barrel 18 is crimped and connected to theshield 62 while being supported on thesleeve 11. Similarly, theinsulation barrel 19 is crimped and connected to thesheath 64 while being supported on thesleeve 11. In this embodiment, thewire barrel 18, theinsulation barrel 19 and the wire-side connecting portion 16 can be crimped simultaneously. In this way, theshield terminal 10 is connected to the end part of the shieldedcable 60, as shown inFIG. 6 . - As described above, the
convex portion 36 shaped to bulge radially outward over the entire circumference is provided in the front pressedregion 33 at the intermediate position of thesleeve 11 in the front-rear direction according to this embodiment. Thus, the flexural rigidity (reaction force) of thesleeve 11 can be enhanced and the insulatingportion 63 can be prevented from being excessively compressed by thesleeve 11. Particularly, since theconvex portion 36 is provided over the entire circumference of thesleeve 11, a circumferentially uniform compression force can be applied to the insulatingportion 63. In addition, since theconvex portion 36 is crushed and elongated by thewire barrel 18, the insulatingportion 63 can be satisfactorily prevented from being excessively compressed by theconvex portion 36. - Further, since the receiving
base 37 along the front-rear direction is provided on the projecting end of theconvex portion 36, theclearance 20 along the axial direction can be formed between the inner surface of the receivingbase 37 and the insulatingportion 63 before thewire barrel 18 is pressed, and the insulatingportion 63 can be prevented more reliably from being excessively compressed. - Furthermore, since the end-side
convex portion 38, theconcave portion 41 and theconvex portion 36 are successively provided one after another from the front end part in thesleeve 11, the front pressedregion 33 is structured to be even harder to crush and the insulatingportion 63 can be prevented even more reliably from being excessively compressed. - The invention is not limited to the above described and illustrated embodiment. For example, the following modes also are included in the scope of the invention.
- The convex portion, the end-side convex portion and the concave portion may be formed, such as by swaging after the sleeve is bent.
- The butting edges of the sleeve may be integrally joined by a joining means such as welding or adhesive. Further, the sleeve may be processed into an endless hollow cylindrical shape in the first place.
- Plurality convex portions may be provided at intermediate positions of the sleeve in the front-rear direction.
- The sleeve may be provided with a convex portion shaped to bulge radially outward over the entire circumference in a part pressable by the insulation barrel.
- The sleeve may be structured not to be pressed by the insulation barrel. Further, the insulation barrel can be omitted from the barrel portion.
- The end-side convex portion can be omitted from the sleeve.
